Personally speaking, I am sympathetic to the idea that billionaires (especially Musk) are often created more by government policy than market forces. Although for some reason the push to stop governments minting billionaires by fiat seems rather weak, which makes me think a lot of people are being disingenuous on the topic. Or maybe just haven't thought about it much. There is a bizarre zeitgeist where first the government has to give a man billions of dollars because something needs to happen ASAP, then they have to take the billions away because nobody thought the thing needed to happen all that urgently.
There is an overlap in the vibe between the people who are unhappy that the government rewarded Musk and the people who, at the time, were clamouring that the rewards for things Musk was doing were too low. 10, 20 years ago it was all "there isn't enough funding for electric vehicles", "world is literally ending from climate change" and "who is going to put money into batteries".
